Here is a note by Sebastien from Qobuz in response to my query. I don’t think this will be a growing problem.
"Thanks for your feedback. We are aware of an issue with the label 2L delivering files in MQA-CD format. This is their standard resolution they send out to all major services in a regular 16/44 WAV file.
This is something we have been working with them internally to change. That is all I can tell you at this time as I am not authorized to discuss internal matters.
Does this help? Don’t hesitate to let us know if you run into any further issues.
Regards,
Sébastien from Qobuz"
